I keep coming across the old LP album jackets (typically early RCA Victor LPM 
series ca. 1955 or thereabouts made from two pieces of thin cardboard) that are 
split open in a flap and only held together by the spine paper.

These are the type where the printed back paper page was glued to the back 
cardboard which it overlapped, then folded over and glued to the front 
cardboard thus holding the two cardboard sheets together.  The front cover 
illustration or graphic sheet was then glued over the front cardboard and 
covered the folded edges of the back sheet.

There is no edge room to use a bead of hot glue to fix these things, and I 
don't want to use any sticky tape which will dry out and eventually fall off as 
I have seen many do in the past!

Years ago, in broadcasting, we used to use white surgical cloth backed tape of 
the kind they used to hold bandages on, but I don't know if you can still get 
that and certainly it would not be cheap!  I still have albums that were fixed 
with that tape that hold up well today, although a clear archival tape with 
similar long lasting adhesive qualities would be good.

Does anyone know of a suitable tape or means to fix these split album jackets?
